Making Audio Enhancers Work on Windows

Status
Not open for further replies.
@alanfox2000 I'm sorry for making a "I just registered this account to ask for help" post, but here we are. I tried installing APO Driver 2.9.5 today, but unfortunately it was not able to solve my problem completely (I was able to get my audio device to register as capable of Dolby Digital sound format, and my receiver actually read it as a valid Dolby Digital signal, but no sound output was actually possible and in the 5.1 surround test tones tool Windows would complain about "unable to send test tone").

I'm trying to "start over," and that's where my question comes in: when I uninstall APO Driver 2.9.5, I choose the "remove" option in the (un)installer, but after the uninstall process completes I still have some leftover "zombie" entries in the Start Menu. All of the DTS and Dolby UWP apps that were unlocked by the "unlock windows store" option during install, a phantom version of those apps seems to remain "stuck" in the Start Menu even after APO Driver 2.9.5 has been successfully uninstalled. Do you know how to remove these "phantom" zombie remnants?

Or anybody else, for that matter. Does anybody know exactly which registry keys get written by the APO Driver installer when it "unlocks windows store apps"?
 
Uninstallation Instruction:
  1. Use "Restore" button under "Endpoint Registry" section for the endpoint(s) that you had use Product Config Tool.
  2. Close any sound enhancers process
  3. Uninstall APO Driver
Source: http://puresoftapps.blogspot.com/2018/04/realtek-apo-driver.html#more -> see bottom of section "Instructions".



You could also use the DriverStoreExplorer (no install needed) to clean all driver remnants.
RECOMMENDATION: Before installing this modified driver, be sure to remove any and all residues from previous Realtek audio drivers or even if there are residues from previous versions of my mods, if they persist. For this you will need the DriverStoreExplorer (by @lostindark). Remove any drivers whose vendor is "Realtek", "Dolby", "DTS", "Creative" or "Alan Finotty" in the Sound, Video and Game Controllers, Extensions and Software Components categories.
... search too for "APO", "DAX".

Best regards
 
Thank you. I thought I had gone through that uninstallation process correctly, but I'll check another time. This should remove the UWP drivers as well?

Untick "driver enhancement" and restart PC could help sometimes this issue.
After that it could work with re-tick this option again.

Try to play with that or other options.

Yes, but you have to do it manually (with DriverStoreExplorer). You are responsable for that. Sorry. :ohwell:
 
You can also send lossless down SPDIF, however, most receiver OEM's are still on the old standard for SPDIF, they don't program the receiver to support more than Dolby Digital and DTS Surround.
The sad part is, most OEM's put in hardware that does 20-125mbps (JIS F05), but don't use it. You can even buy 125mbps rated JIS F05 cables that directly support lossless formats.

In short, even if you fully unlock your SPDIF, you will not likely find a supporting receiver, even receivers that handle lossless down HDMI, don't down SPDIF.
My ALC 889 has the similar limits as HDMI in terms of PCM audio processing (1,152 aggregate), but up to 125mbps bitstreaming.

ALC 889 (2008) SPDIF: 6 x 192khz = 1,152, it can also do 8 x 96khz = 768, but not 8 x 192khz = 1,536.

@Ferather, how can I do for "unlockin' my S/PDIF"?
 
You need the format support reg edit for Atmos, although I have not tried it, because I know most OEMS don't currently support it on Toslink.
To send lossless formats (DTS-HD MA, TrueHD), Dolby Digital Plus and DTS-HD HRA, just set Potplayer to WASAPI exclusive.

You can try other media players, but you want WASAPI exclusive, and sometimes event driven.

Isn't the AIMP-Player from Артём Измайлов (Artjom Izmaylov) even possible too for this Unlocking? WASAPI will be supported

Unfortunately, even after deleting all UWP drivers with DriverStoreExplorer, the start menu remains populated with broken "zombie" installations of the corresponding UWP apps.
 
@driverNoob
Please deactivate the 'auto update apps' by M$ Store.

If you still have problems with that, try BulkCrapUninstaller.
You could also delete registry keys of the UWP apps with that tool.

If that not help you, I don't know more what to do.
I never used this version of APO. It's some years ago, that I used APO.
 
I need some help with getting 5.1 working again on my setup. I am running an hdmi 2.1 cable from an Nvidia 3090 to a LG C1, that then runs through earc (firmware update to earc) into a Yamaha rx-v683 receiver.

I was using the apo driver method to enable dolby digital which was working well, until it stopped working. Now selecting dolby digital just brings up the "format not supported" error. I have tried fully uninstalling the apo driver (including all leftovers) and re-installing several times, but dolby digital still gives that error. I would run the PC through the receiver, but since it isn't hdmi 2.1 I lose the ability to run 4k 120hz

Is there any setup for apo that is working for most people? (especially on Nvidia driver 471.41) Or are there any other ways to output 5.1 through Nvidia hdmi?
 
Or are there any other ways to output 5.1 through Nvidia hdmi? - Does it have to be Dolby Digital Live? Or can your receiver decode DTS Surround?
 
Hi guys, Where I can find UAD Driver + Creative Sound Blaster Connect 2 only?
Thank you
 
Ask @Alan Finotty, he has an array of APO's, hopefully its version 2 'Creative Sound Blaster Connect' he has, else I don't know sorry.
If he has the files, at times, he might be able to compile an extension, or already have one you can use.

He stopped using an installer and instead, like myself, uses the open method (you can see the files).
 
Anyone have experience with the APO / FX Configurator HDMI home theater v4 on the Windows 11 preview ring?

Hi all!!

first of all sorry about my poor english and for opening this account only for some support.

I'm struggling with my TV passthroug 5.1 audio to my AVR. My current configuration is this:

PC->TV->AVR (all HDMI connections)

Sound Card: Integrated Realtek
Video Card: Nvidia Geforce GTX 1080 ti
TV: LG OLED CX
AVR: Onkyo TX-NR535

I have been able to play media from the TV in 5.1 channels to the AVR without problem, but I can't make my windows detect 5.1 sound throug HDMI connected to the TV (passtrhoug is configured OK) over the AVR. I guess I'm doing something wrong but all my tests have failed and I don't know how to manage to make it work after thousands of tries and driver install/uninstall. Could someone tell me how to solve this please?

If there is some other info I can provide just let me know.

Thanks a lot.
